Argo Tunnel + DC/OS

Cloudflare is proud to partner with Mesosphere on their new Argo Tunnel offering available within their DC/OS (Data Center / Operating System) catalogue! Before diving deeper into the offering itself, we’ll first do a quick overview of the Mesophere platform, DC/OS.

What is Mesosphere and DC/OS?

Mesosphere DC/OS provides application developers and operators an easy way to consistently deploy and run applications and data services on cloud providers and on-premise infrastructure. The unified developer and operator experience across clouds makes it easy to realize use cases like global reach, resource expansion, and business continuity.

In this multi cloud world Cloudflare and Mesosphere DC/OS are great complements. Mesosphere DC/OS provides the same common services experience for developers and operators, and Cloudflare provides the same common service access experience across cloud providers. DC/OS helps tremendously for avoiding vendor lock-in to a single provider, while Cloudflare can load balance traffic intelligently (in addition to many other services) at the edge between providers. This new offering will allow you to load balance through the use of Argo Tunnel.

Quick Tunnel Refresh

Cloudflare Argo Tunnel is a private connection between your services and Cloudflare. Tunnel makes it such that only traffic that routes through the Continue reading

Continuous Integration in Network Automation

In the first part of his interview with Christoph Jaggi Kristian Larsson talked about the basics of CI testing. Now let’s see how you can use these concepts in network automation (and you’ll learn way more in Kristian’s talk on April 9^th… if you register for our network automation course).

How does CI testing fit into an overall testing environment?

Traditionally, in particular in the networking industry, it's been rather common to have proof of concepts (POC) delivered by vendors for various networking technologies and then people have sat down and manually tested that the POC meets some set of requirements.

New Year, New Home

We have left the Bay Area, and headed North. We have moved to the Greater Seattle area - specifically the Eastside, between Bellevue and Redmond. We’ve given up the old apartment in San Francisco for a larger, nicer house…for a lot less in rent. A lot fewer bars & restaurants, a lot more trees, parks and lakes.

But Why?

The typical Bay Areas response is: “But why??? It rains all the time in the Pacific Northwest!!!!”

A few things:

1. Yes, it rains more here than San Francisco, but not as much as people think. It’s not even in the top 10 cities in the US for annual rainfall. Boston, New York, Washington DC all receive more.

2. Rain is OK. In fact rain is good. You don’t get lush forests through irrigation. You also don’t get clean streets just from street sweepers. 

The main attractions for us are:

• Much better lifestyle for us. It’s easy to go mountain biking, running, hiking, skiing here.

• Much lower rent. Yes, rents have gone up a lot here, but it’s still much better value than San Francisco. I pay much less rent here, but I get a nice place, and the Continue reading

Docker and Netdata – Awesome for Monitoring our home servers !

I don’t belong to any DevOps space but I keep hearing things like Docker / kubernetes and what not. I Quickly wanted to see what these are capable of and if I can use them to my advantage so that later I can see the use case for networking.

Docker so far seems to be far more capable and am enjoying it. Thanks to one of my friends who suggested this wonderful Repo, monitoring my server has been more granular.

I will have a detailed post on Juniper MX image via docker but for now, I have used it for something out of networking space to serve a small purpose.

https://github.com/netdata/netdata

This what Netdata UI looks like while monitoring my server, this is really wonderful as for the long time  I was trying to implement many Monitoring systems and most of them required some dedicated hardware or at least a Vmware spin-off instance, which is fine for me I suppose but I wanted something small and yet effective.

Netdata operates on port 19999 of localhost and should be reachable via any web-browser.

I made a small cronjob which starts this instance on every reboot.

Installation is pretty straight forward, Continue reading

SUSE releases enterprise Linux for all major ARM processors

SUSE has released its enterprise Linux distribution, SUSE Linux Enterprise Server (SLES), for all major ARM server processors. It also announced the general availability of SUSE Manager Lifecycle.SUSE is on par with the other major enterprise Linux distributions — Red Hat and Ubuntu — in the x86 space, but it has lagged in its ARM support. It’s not like SLES for ARM is only now coming to market for the first time, either. It has been available for several years, but on a limited basis. [ Two-Minute Linux Tips: Learn how to master a host of Linux commands in these 2-minute video tutorials ] "Previously, SUSE subscriptions for the ARM hardware platforms were only available to SUSE Partners due to the relative immaturity of the ARM server platform," Jay Kruemcke, a senior product manager at SUSE, wrote in a blog post announcing the availability.To read this article in full, please click here

Linux systems: Scraping up information about apt updates

When you use the apt command to install new packages or run routine upgrades on your Debian-based Linux system, you might wonder where information about your activities are being recorded. For one, your history file probably retains information on the commands that you use, though history files like ~/.bash_history will only keep the most recent commands that you've run — depending on your $HISTSIZE setting — and generally will not include dates and times. There is, however, another place to find information about apt commands and that place is /var/log/apt.The /var/log/apt directory contains a number of log files — the history.log file, plus a series of older versions of the file named history.log.1.gz, history.log.2.gz, history.log.3,gz and so on. Each of these logs will contain information on apt commands that have been run within a particular timeframe.To read this article in full, please click here

Huawei introduces AI-driven data center switch

Chinese telecom giant Huawei introduced a new data center switch powered by an artificial intelligence (AI) chip designed to improve performance and reduce latency to near zero. The new switch follows the announcement of a 64-core ARM server processor.The CloudEngine 16800 series of data center switches use AI to improve network operations and also provide an underlying network foundation for companies to build new apps that utilize AI for network performance.Huawei claims the CloudEngine 16800 is the first data center switch use an embedded AI chip, using the iLossless algorithm to implement auto-sensing and auto-optimization of the traffic model, thereby lowering latency and providing higher throughput based on zero packet loss.To read this article in full, please click here

Understanding the JunOS routing table

I was just about to finish another blog post on MPLS when I got a question from a colleague about Junos routing tables. He was confused as to how to interpret the output of a basic Juniper routing table. I spent some time trying to find some resource to point him at – and was amazed at how hard it was to find anything that answered his questions specifically. Sure, there are lots of blogs and articles that explain RIB/FIB separation, but I couldn’t find any that backed it up with examples and the level of detail he was looking for. So while this is not meant to be exhaustive – I hope it might provide you some details about how to interpret the output of some of the more popular show commands. This might be especially relevant for those of you who might be coming from more of a Cisco background (like myself a number of years ago) as there are significant differences between the two vendors in this area.

Let’s start with a basic lab that looks a lot like the one I’ve been using in the previous MPLS posts…
